Travelling guitar.

TBH, what I know and how I've learnt it, has been very much from "paint by numbers" electronics. (connect wire A to lug X, now connect wire B... you get the idea :o)

The volume of electronic theory I possess would struggle to fill a thimble, but I manage to make things work and troubleshoot when needed.
I have just basically taken it on faith that the middle lug was always output, can't necessarily tell you why.

Also, we should be clear on how we refer to the lug numbers. TTBOMK, this is the accepted distinction:

Attachment 35380

That's the numbering I was referring to, I was just too lazy to find some pictures.

Thanks everyone. Between the posts and countless YouTube videos I’m getting somewhere (I think).

Ok, here is my first soldering attempt. Just like the diagram (?). The white wire is on the middle volume tang but looks like it’s on the side tang due to the shrink wrap and camera angle.
I get a little hum when I plug it into the amp, but it does pass the tap test.
Hoping for some comments before I heat the shrink wrap. Is there anything I can do with my newly purchased multimeter at this stage?

Where's the output ground wire connected to, or was that done after the pic was taken?

Have you shrunk the heat shrink yet?

Output ground wire?

Heat shrink not shrunk yet.

You've got a black wire on the output jack, but I can't see it leading to the back of a pot.

I thought that was supposed to go to the bridge.
Are you saying the black (ground) wire from the output jack needs to return to the back of one of the pots (volume or tone?) and another ground wire needs to be soldered from the back of one of the pots (volume or tone?) to connect with the bridge?

Indeedy!

That way it works. Ground wire to the bridge helps stop buzzing when installed, but the ground wire to the pot is the much more important wire.

Ok, so which pot should the black wire from the output jack return to? And which pot should have a wire to the bridge? Or does it not matter which pot is used?
